Answered by Ms. Sue
The problem is that you left something out of the problem.

This doesn't make any sense:

" is being completed at space of one-length of its length"
Answered by Kristine
A 8-kilometer roadway under construction is being completed at a pace of one-tenth of its length per week. After 5 weeks, how many meters remain to be completed?
Answered by Ms. Sue
Ahh -- one/tenth of its length makes sense!

What do you think the answer is?
Answered by Kristine
4000
Answered by Kristine
one-tenth 10%?
Answered by Kristine
1/10 ?
Answered by Kristine
its 4000 or 40 its between those two
Answered by Ms. Sue
0.1 * 8 km = 0.8 km = 800 m per week

5 * 800 = _______ m
Answered by Ms. Sue
That answer tells you how many meters are completed in 5 weeks. Now, subtract that from 8,000 to find how many meters need to be completed.
